The advantage of Two Pieces Can compared three pieces can in food packaging

March 07, 2022

Two pieces of stamping pot, is the most important characteristics of the side wall and bottom of the can body is an integral structure, no seams, so relative to three cans has many advantages:

(1) the content security. Full jointless can wall, has a complete internal coating protection at the same time, wipe the body welding line and the bottom cover the possibility of a seal leak; At the same time, the body can make seamless body and pot cover sealing is more reliable, high air tightness, ensure the safety of the contents

(2) the printing effect is good. 2 pieces of stamping jars of seamless, can full printing, the lateral uniform smooth, ought to enhance the printing effect, and then the designers design logos and diagrams is beautiful; At the same time, the two cans with perfect appearance of soft, smooth lines, has a good artistic effect

(3) the second piece of stamping can compared with other metal cans with volume, has the characteristics of light weight, save material.

(4) molding process simple. According to the technical requirements can be a stamping molding or continuous stamping forming. Forming speed, can realize mechanization, automation, high speed, high efficiency of continuous production.

Two cans of defect is:

(1) two piece cans of equipment investment is large, the material demand is high, you need to use the ductility can be a good material.

(2) the mold factors such as limit, two cans of single can type, difficult to adapt to the requirement of many varieties, diversification.

(3) the compressive strength is low, commonly used for gas filling or carbonated beverages products have certain internal pressure to keep the strength of can, relative to the three pieces can deformation more easily.
